This CURT adjustable channel-style ball mount has a shank size of 2" x 2" and features two different trailer ball sizes to accommodate two different coupler sizes: 2" and 2 5/16". It also features an adjustable shank assembly with multiple mounting holes for varying ball heights. Each trailer ball can be raised to a maximum of 5 1/4" rise or lowered to a maximum of 6" drop, allowing you to make your trailer completely level in any towing situation. The channel-style design and dual-pin mounting system also provide a built-in anti-rattle feature to eliminate obnoxious chucking noises.

This CURT adjustable ball mount offers a gross trailer weight capacity of up to 10,000 lbs. for the 2" ball and 14,000 lbs. for the 2 5/16" ball. It allows you to tow a variety of heavyweight trailers, and it features two pin holes in the shank to be mounted at an 11" or 12" length. The adjustable channel-style shank can also be used with the channel-style combination pintle mount or ball mount platform attachment to give you the option of installing your own trailer ball size.
